It is recommended that the ALEXSEAL ® Topcoat be appliedwithin 4 days (2 days if outside) after sanding to ensure adhesion.2. Apply 2 - 3 coats to a wet film thickness (WFT) of 2 - 3 mils (50 - 75 microns) percoat. Allow 20 - 60 minutes tack up between coats. This will achieve a dry filmthickness (DFT) of 1.5 - 2 mils (30 - 50 microns) for a 2 coat application. For a 3coat application, this will achieve a dry film thickness (DFT) of 2 - 3 mils (50 - 70microns). Maximum recommended film thickness during a spray application is 3coats totalling 12 mils (300 microns) WFT, or 4 mils (100 microns) DFT. Pleaserefer to the “Technical Data Sheets” starting on page 64 for detailed applicationinformation regarding film thickness and recoat times.Procedure For Application of ALEXSEAL ® Premium 501 Topcoat By BrushAfter applying ALEXSEAL ® Finish Primer 442 according to the procedure in the“Technical Data Sheets” starting on page 64:1.

ALEXSEAL ® singlestagemetallic finishes produce a dramatic effect that creates a metallic, glossy surfaceusing a single-stage polyurethane. This is achieved using one of the Premium Topcoat501 metallic colors and – as opposed to the M Series paints – does not require clearcoating, but allows the applicator the option to apply clear coat if desired.Important:DO NOT use single-stage metallic (T Series) topcoats on large surfaces, asthey are more prone to producing mottling or an uneven finish in the metallicover large areas. For larger surface areas, the M Series metallic coatings shouldbe used.
